AE sliQWndn -tlie drawings, the sleeping bag assembly comprises three principal elements: the outer casing 5,' inner mattress 6, and sheeting 1, each shown in opened position in Figs. 796 and 4 respectively. The outer casing 5,'as depicted in Fig. 7, in opened position, is preferably of balloon and A cheese cloth construction, and has incorporated 55 thsrein restiiers my dawn oi otliet G ifi stasis facile assembly of the sleeping bag.

at 31 to receive loops 22 and to permit tapes 23 of flap In to be drawn therethrough making for Referring particularly to Figs. 2, 3 and 8, the outer casing 5, inner mattress 6 and sheeting 1 are assembled by means of the various tapes and loops; the'units are then folded together; and

tr sses q slide fastener parts [6 and H of casing 5 are closed, thus securely fastening the otherwise open side and bottom of the bag, leaving the head end open for access of the occupant. It will be noted that in this stage, sheeting I covers all portions of the bag which may contact the body, head and face of the occupant.

In mild temperatures, the inner mattress 6 (Fig. 3) may be removed entirely or folded under sheeting 1, using only upper fold 8 of the outer casing 5 and fold 30 of the sheeting l as a covering.

In extreme cold, further protection to the head and shoulders is furnished by flap H), which may be drawn over the head, face and shoulders of the occupant and adjusted to suit. It may be positioned by tucking the flexible edges of flap l 0 over and around the head and under the flexible edges of the upper mattress assembly. Or it may be loosely held by the hand or hands holding tie tapes 23 or by the same tie tapes being passed under the sheeting tie tapes, and drawn taut but leftuntied, fora friction hold, With theflap I0,

thus arranged, guick exit from the bag may be hadby merelyfpushing the'flap from the face and head, dragging thejunfastened tie tapes 23 from the sheeting tie tapes3 6.

The occupant may leave tapes 2| untied and usethe slit, provided in each of the upper folds of the members. This slitserves as an aperture for the face,while the two sides cuddle theface and shoulders. in a manner not ordinarily .possible.

With my sleeping bag theoccupant may rest in comfort on his back or turn from side to side without rolling the entire bageor, disturbing the general adjustment offlap 9. One may breathe easily the outside atmosphere through a suitable,

channel arranged along the lower edge of the flap. Furthermore, because pf the inherently flexible n ature of the flap,.it.may be adjusted to.

suitan occupant of any height.

, Eminentlysatisfactory results are obtained by use of my sleeping bag; economy of manufacture; the health of the occupant may be; safeguarded by changing or cleaning the sanitary sheeting.

In.its broader aspects the invention comprises not only thevarious means described but equivalent meansffor performing the recitedfunctions.
